21. The bond dissociation energies for F2 and Cl2 are approximately 158 and 242 kJ mol−1, respectively. Given that the enthalpy change for the reaction below is ΔH = −54 kJ mol−1, what is the bond dissociation energy for the F-Cl bond? ½ F2(g) + ½ Cl2(g) → FCl(g)
A 200 kJ mol−1
B 254 kJ mol−1
C 146 kJ mol−1
D 454 kJ mol−1
E 346 kJ mol−1
